And here are the results of UV's Genesis XOC based on Intel’s QX6850 quad core processor overclocked to 3.50GHz. The graphics are handled by two EVGA 8800 Ultra Black Pearl cards, coupled with 2GB OCZ Reaper memory and Western Digital Raptor disks in a RAID 0 setup.
One of the first tests we’ve done was 3DMark03 where we tried to show the advantage of using two cards in SLI mode. The actual advantage was slightly over 40%. It’s unlikely that any test will score a double or at least close to double the performance of a single card. Still, 66465 marks are quite respectable.
A surprisingly low result; 3DMark05 shows speed increase of just 11.5%.
3DMark06 utilizes SLI a bit better; we got a 31% boost compared to using just one card. 18175 is a result you don’t see every day.
We downclocked the processor to 2.67GHz, and this, of course, resulted in less frames per second. Overclocking the processor will yield up to 40 fps more.
QX6850 in Genesis XOC runs at 3.50GHz, so its results should resemble the ones we got with QX6700 processor overclocked to 3.50GHz. The rest of the components are identical to the ones listed in the sample.
The score difference when using two cards in SLI as opposed to using just one was around 51%. That is a good sign, since the synthetic tests showed very little improvement.
Antialiasing and aniso filtering require some serious muscle, so the SLI system scores 68% more compared to a non-SLI system.
You can check the power consumption of such a system in the tables below.
We mentioned that GenesiXOC packs a NorthQ Giant Reactor 1000W PSU, which will keep you on the safe side away from overloads. The whole system required maximum 672W. In idle mode you’ll get around 431W.
